SmroNs, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have in- My invention relates to that class of crushing machines, 'haviiigan outer bowlshaped frame or shell, inside'otl which 'isan oscillating,r crushing-head surrounding a cen-A trallylocated shaft.

The objects of my invention are, 1st; to so arrange the supports and bearings of the ccn- 'tral shaftas to exclude dust therefrom, and 15.

reduce friction; nd, to improve the means for lubrication; 3rd,' to improve the manner of supporting and adjusting the crushing. head; and 4th,' to coiisti'uct'a-siiiiple and efficient machine, having its parts of-wear easily replaceable. I My invention consists 'of the novel `construction, arrangement, and combinations.

throughout the several views.

1 is Athe outer shell or frame to which the spider-armed crown-piece 2,` is fitted land securely bolted.- The spider-armed bottom 3, is preferably castas apart of said Jframe, lalthough it may be made separately vand i fitted to the body of the shell after the man,- ner of thecroWn-piece. The main central ,shaft 4', is surrounded by three rollercollars, after the nianner of roller bearings. ','Ihe upper roller eollar is contained within the erown-piece 2, and'c'ompri'sesrolls 5, set

loosely in the cage 6.- The .middle roller collar 4is substantially contained within the kcrushing-head 7, and comprises the rolls 8 `set'loosel'y in ,the roller-cage 9.`v And the lower roller collar; comprising rolls 10, set within cage 11. is contained Within spiderarmed bottoin.3, of the main frame.

12 is a dome dust cap, fitted over the oil receptacle formed by the casting 13, which is :fastened to the crown-piece and prevents an upward movement` of the adjacent rollereollar and the shaft 4'.

The sleeve 14,'detailed in F ig. 6, loosely surrounds shaft 4, -is' carried upon the' roller- 'cage 9, and supports the roller-cage 6 together with rolls 5. The roller-cage 9, ada pted to hold the rolls S in proper alinenient, is carried on the'liub ofthebevel gear wheel 15, whieh'is keyed in tlieiisual way to shaft inner legr of the angle-ring 1G, supported by and bolted to the spidei.' armedv bottom 3. 'The outer angle-ring. or adjusting ring 17,' Ci s held by its spiral tongueland-groove, or fhreaded engagement with the ring 16 (see Fig. 4) and in connection therewith protects -ear-wheel 15. and affords a support to the free to slide upon' ring 17. The hooked lbar- 18, pivotally conneited to ring 16, at 19, may be i'na'de to engage with any one of thelugs latter in desired position. The lugs 21, on ringf 17., are made vconvenient for the application thereto of a wrench V22. used in turniner said ring for vertical adjustment of the '-erusliinfz-head. The stud-bolt.. or pin, 23,. projecting: f roin the lower end of shaft 4,

' together with the Wearing-plate 24, aiords -soeiated parts shown in section. Fig. 9.is a detail sectional plan taken on line AAB,

iinilar figures relate to similar parts i vented a new and useful Crushine-Machine, .of which the following` is a specification.

"i 4, and which has a lower end bearing on the crushing-head 7, which. in its oscillation, is.

Q0, projectingr from the ring 17. to hold the a. suitable end-bearing. to sustain the weight of said shaft. I' l Recessed in crovvn-piece2pare'the holes' 25, for receiving 'the adjusting bolts 26 5*-Which, in connection .withthe nuts"27,'l

The dies, or concaves, 29, are removably` Secured in frame 1, opposite to the crushinghead ,7, to formv the .crushing-hopper.V The pinion. 30, engaging with the 'bevel gear Wheel 15, for driving shaft 4, is preferably keyed to; shaft 31, which .is supported by --its bearing 32, inframe l.' -Shaft 31 is pro- -vided with the .belt-Wheel 33 secured thereto for the application of power.

'20 That part of 'thema-in central shaft 4 which issubstantially contained within the crushing-headas shown in Fig. 2, is preferbly made eccentric to the center line of its end bearings, in which the rolls 8 are of like size., In thev other and equivalent form of this eccentric device "shown in Figs.

v8 and 9, the main shaft 4 is made of uniform diameter throughout, and the rolls 8,are

so graduated to suitable diameters as 'to f3.0 allowv.- each of said rolls to maintain substantially continuous lines'of contact both with shaft 4, and -With the inner surface of the crushing-head 7,'-when thelatter is ec- 35 c elntically positioned encetosalid ;.sa..

'-'g'lhe wheel 34'siupported by bearings 35,

connected to the main frame, isdriven-in frictional contact with the shaft 31 and so operates through the common crank device shown to drive the oil-pump36 bolted to Yoil-tank 37. 38 is an. oil-pipe connecting pump with the oil -receptacle in casting i-i3.. 39 is a ret-urn oil pipe connecting the T-.goil basin, provided in the lbottom B, with .5 said yoil-tank. t I 1 1. 1, Inthe' operation-of my crushing-machine the central shaft' 4, is 'made to rotate through means'provided therefor as shownl and described.' This rotationI of 'shaft`4 cause'sthe, Q0 rolls '8 to travel around said s'haftand there- .by impartto the crushing-head' an oscillat- "ing j or crushingl .movement whereby stone placed in the crushing-hopper is broken or crushed to sizes permitting it tofallsthrough i the dischargepeniiig at the bottom. of said` f-,ahoppen' VWhen ,it is desired to .decrease the iwidthyf s'aid tiiscluirgef'.o ening, the operator, by turningI th' e.1 iut sl` 2 lowers them -to .alloiv auf upward movement-.of said crush-y ing-head. Thehook 18, being then disengagecl, the lcrushing-head is 4raised by .turn- 'm'g the ring..1 7, on its spiral zsupport to the desired point oaadjustment, when hook 18` ='-.5is again .llgged With one'pf the lugs 20. @During this :operation th'e bolts 26 enter farther into. the recesses. 25. tlhel nuts 27 I are then-brought again in contact Withthe crovvn-piece.- 1

Reversing the operation described 'increases the' bottom opening of the "crs'hinghopper alloivi'ng a 'coarser product. ij

Since provision for' thorough and contin- 'uous lubrication is absolutely essential to -th'esuccess ofa machine of-this type, an

important feature of therollercollars surrounding shaft 4, is' that they afford between the rolls passages or conduits, for the free circulation. of oil, Which-passages I-have arranged tomake continuous along thev entirelength of shaft 4 by the peculiar construction of-sleeve 14 as described and by opening free communications from. both the ity formed by the frame and angle-rings as shown in the drawing .and as set forth. This cavity constitutes a'basin for the collection of oil and insures the lubrication of middle and lower sets of rolls, into the cavf the gear-Wheel'and pinion. The circulation of oil through said conduits is effected by means ofthe oil-'pump 36,'driven as hereinbefore described, and which forces the oil into the receptacle in casting 13, whence by gravity :the oil finds its Way'thrughpaS- sages indicated by the arrows (Fig. 2,) into thence through pipe 3.9, into tank 37.
